I don't have anything specific in mind, but when I'm looking for pretty tees, I usually look at tops from Velvet. They usually have interesting details like ruching, and they're super comfortable. There are some on sale at revolve right now, and there's a 20 percent off code: people20.
I picked up this tee-shirt in black from Target yesterday for $14.99. It's really cute on! I did size down because they tend to cut their items a bit generously.
